WALL, CEILING OR ROOF ELEMENT CONNECTION
A wall, ceiling or roof element connection for connecting bar shaped, beam shaped or panel shaped wooden components includes a pin arranged on the first wooden component and has an outer contour widening in the direction of the second wooden component, and a recess or notch arranged directly on the second wooden component and having an insertion section for insertion of the pin and a holding section having an inwardly widening inner contour adapted to the outer contour of the pin for holding the pin. The pin is attached to the first wooden component via a detachable connection.
The invention relates to a wall, ceiling or roof element connection for connecting bar-shaped, beam-shaped or plate-shaped structural elements.
BACKGROUNDFor the connection of wall, ceiling or roof elements, special metal connectors or classic wood connections with e.g. finger or dovetail galvanizing without metallic connecting elements are often used in wood construction. In the case of conventional dovetail joints, a pin with a specially shaped outer contour is usually milled or cut out on one component. On the second component, a corresponding groove is produced with an inner contour corresponding to the outer contour of the pin. The lateral exterior surfaces of the pin and the corresponding inner side surfaces of the groove are generally chamfered, so that the pin and the groove have a dovetail shape in cross-section. As a result, such a connection can transmit not only transverse forces but also tensile forces. However, the production of such a connection involves a correspondingly high production expenditure. In addition, a relatively large amount of material would have to be removed to make the pins when connecting large-area components so that the pin remains. Metal connectors also tend to be laborious to fabricate and require accurate pre-assembly. In addition, in the case of wall fastening, the insertion with such metal connectors is relatively difficult, because the clearance is very small.
SUMMARY OF THE INVENTIONOne aspect of the invention relates to create a wall, ceiling or roof element connection, which enables a simple and cost-effective connection of even large-area construction elements.
Useful further developments and advantageous embodiments of the invention are disclosed herein.
In an embodiment, the wall, ceiling or roof element connection according to the invention comprises a pin arranged on a first wooden component and having an outer contour widening in the direction of the second component, and a recess or groove provided on a second wooden component and having an insertion section for inserting the pin and a holding section with an inner contour adapted to the outer contour of the pin and widening inwards for holding the pin. The pin, which is formed as a separate component, is secured to the first component by a detachable connection, e.g. configured as a screw or pin connection. The recess or groove associated with the pin is arranged directly in the second wooden component. It may, for example, be milled directly into the second wooden component. Via the detachable connection, the pins can, for example, be mounted easily and quickly at any desired locations. No complex manufacturing or assembly steps are required. For example, corresponding pins can also be relatively easily attached to the end or side surfaces of large wall components at the desired locations. This can considerably simplify the assembly of large-format components, such as wall, ceiling or roof elements made of wood. Compared with known metal connectors, the wall, ceiling or roof element connection according to the invention also offers improved freedom of movement. When attaching the connection, the components can be aligned and adjusted even more easily, making assembly considerably easier. Both the pin and the corresponding recess or groove can be manufactured easily and inexpensively, providing an economical connection with significant time savings during assembly.
In a particularly practical embodiment, the detachable connection can be designed, for example, as a screw or pin connection with one or more screws, studs or other similar fastening elements. The pins can be easily and quickly mounted at any position using the screws or corresponding fastening elements and can also be relocated or readjusted if required.
According to one possible embodiment of the invention, the pin has a cross-section widening from an inner connection surface facing the first wooden component to an outer front surface facing the second wooden component, and the holding section of the recess or groove has a cross-section widening inwards from a front exterior surface of the second wooden component. Such a contour also allows tensile forces to be transmitted with high stability.
In order to achieve a secure and precisely positioned connection between the pin and the first wooden component, an elevation, e.g. in the form of a feather key, can be provided on the inner connection surface of the pin facing the first wooden component for positive engagement in a corresponding depression on the first wooden component.
The wall, ceiling or roof element connection can be designed as a dovetail connection with inclined outer side surfaces on the pin and correspondingly inclined inner side surfaces in the recess or groove. In a particularly stable and load-bearing design, the pin may be in the form of a wedge tapering in the insertion direction. However, the pin may also be in the form of a truncated cone or in the form of a block-shaped insertion member of uniform cross-section.
In another possible embodiment, the wall, ceiling or roof element connection can also be designed as a T-connection with a T-slot and an associated pin with a T-shaped cross-section.
The side surfaces of the recess or groove and also the exterior surfaces of the pin expediently extend toward each other in a wedge shape in the insertion direction of the pin. However, the pin and the recess or groove can also have a constant cross-section.
The pin can conveniently be made of wood, preferably laminated veneer lumber or hardwood, but it can also be made of plastic or metal.
Further features and advantages of the invention will be apparent from the following description of a preferred embodiment based on the drawing. It shows:
